How well does it erase? I love it.

Hmmm. I am thinking this was the massive amount of PB blaster I soaked the studs with burning off. By the time I was finished removing the exhaust manifold it was coated in the stuff. Anyone else have a similar experience?

Ok, so everything is back together. I fired up the engine and it ran great. Sounded better than before. But as the engine gets hot smoke starts poring out of the engine compartment. "I don't think this is an exhaust leak as I see nothing until the engine gets hot. it will continue to smoke till the engine cools down. I am scared.

fast woman, What type permatex sealant did you use? my new gasket is a fel-pro. Looks sort of cheazy, paper bonded to metal.

No need to wash or wax, just erase! But really out of all the cheap paint jobs I think I like this one the best.

I got the manifolds removed today. The bolds and nuts seemed to easy to remove like they were not torqued down at all. the old gasket was in pretty bad shape, it looked as though someone in the past had removed the manifolds and reused the gasket damaging it in the process and there was a piece missing from cylinder one's exhaust. This makes me happy in a way as I feel I am doing this for a cause instead of a hunch.

The four top bolts are accessible. most remaining are not. The intake manifold on a 280z shares some bolts/studs with the exhaust manifold. I have stopped being a baby and managed to remove to heat shield. There was no mention of this problem in my search on this sight or elsewhere. So if anyone else runs into this dilemma I have a few tips. first remove any component you have to first, such as the PVC tube, the AFM and boot etc. Second the heat shield is in two parts (my stupid). if you can, remove the lower heat shield first (rusty phillips machine screws). and finally take your time, use bad language, don't think about barking you're knuckles or scratching you're forearms raw for four 12 mm bolts (use a wrench, sockie no fit).

No way.

I think this is more difficult as my Z is fuel injected and there is no way to get at the heatshield bolts. :angry: I was thinking of using copper spray, still thinking....

Thanks fastwoman, I am familiar with tapping holes in steel and aluminium. We use Kroil at work, Great stuff but it seems a can stops dispensing after 1/4 use. I don't know why. So now I am getting ready and I am F%&%&CKing stuck. the @$#%#!$% heat shield is in the way and it appears to be bolted to the underside of the intake. Any suggestions? my hands are not large but I can only just get them in far enough to touch the bolts.

Just a thought, could it be a bad water temp sensor or connection? this will affect the mixture. You might be compensating for it with the spring adjustment. I see you replaced yours but you could still check it with a meter. Also have you checked the AFM flap to see if it is sticking? I am just suggesting these because they are problems I have run into. edit.. The more I reread youre post and think about it it seems the problem is the AFM. "often in the rundown from vigorous acceleration, or on the way up in moderate acceleration, the accelerator feels "clunky" for a moment before clearing up." this sounds like a sticky flap. I could be way off, but it makes sense to me.

Does you're car have the ac dash-pot thing that is actuated by vacuum? it should increase the throttle.

If it is a 280z dash, it is worthless. I will dispose of it for free + shipping.

I see three guys and the legs of one of those grey aliens.

Shiny! verry sparkly! shiny! shiny!

Changing the mounting hardware makes sense especially the exhaust. looking up the Nissan part now.... cannot find genuine Nissan gasket. Nippon Reinz?

Funny, I already saved that article you wrote to my favorites two weeks ago. I was wondering about anything that I may need to apply to the mating surfaces. I used a copper spray when putting head gaskets on my Kh400 but that was a two stroke motorcycle.

I am planning on replacing the manifold gasket on my 77. Any advice from those who have done this before? I plan on giving all of the bolts a liberal soak with PB blaster the day before. What brand of gasket is best? What snags should I expect? ect.

It can be fixed. new rear fender and a new roof. not impossible.

ya mine were rusted also. It's funney how some parts are so hard to find.

Nice start. Looks like you may see some body work soon. is that rust on the ground? Cute puppy.

sorry I did not mean to confuse the issue. I was thinking he disconnected the water temp sensor instead of the sender ujjjjjjjjh (cat walked on keyboard)

not sure the video helps at all. The photo is more than enough. From what I can tell the bearings flew off. Those are bearings, not plugs. they are held in by clips. were they not installed afer pressing them in? You do not need a machine shop to replace these. you can use a c clamp. Hard to tell but if the clips were not put in that would explain why they flew outwards.

Oh, My car is a 280 with the park benches, so I am unfamiliar.
